Answers

The common domain for the variables is; It is true on every set with no more than 22 members and false on other sets.

What is the domain of the variables?

We are given the statement;

∀x∀y((x ≠ y) → ∀z((z = x) ∨ (z = y)))

Since x and y are different objects in the domain, then we can say that anything in the domain is equal to x or to y.

Now, If the domain M has two elements, it means that the given sentence will obviously hold. Also, a one-element domain will work since there wouldn't be a pair x, y such that x ≠ y.

We can conclude that the common domain for the variables is; It is true on every set with no more than 22 members and false on other sets.

What is the molar solubility of agcl (ksp = 1. 80 × 10⁻¹⁰) in 0. 500 m nh₃? (kf of ag(nh₃)₂⁺ is 1. 7 × 10⁷)

Answers

Based on the calculations, the molar solubility of AgCl in 0. 500 M of NH₃ is equal to 2.77 × 10⁻² M.

Given the following data:

Ksp of mg(oh)₂ = 1.8 × 10⁻¹⁰Concentration of NH₃ = 0.500Kf of ag(nh₃)₂⁺ = 1.7 × 10⁷

How to determine the molar solubility.

First of al, we would write the properly balanced chemical equation for this chemical reaction:

                          [tex]AgCl(s)\rightleftharpoons Ag^{+} (aq)+ Cl^{-}(aq)[/tex]       Ksp = 1.8 × 10⁻¹⁰

                [tex]AgCl(s) + 2NH_3(aq)\rightleftharpoons Ag(NH_3)_2^{+}(aq)[/tex]   Kf = 1. 7 × 10⁷

K = Ksp × Kf

K = 1. 80 × 10⁻¹⁰ × 1.7 × 10⁷

K = 3.06 × 10⁻³

Mathematically, the Ksp for the above chemical reaction is given by:

[tex]K=\frac{ [Ag(NH_3)_2^{+}][Cl]}{[NH_3]^2}\\\\3.06 \times 10^{-3}=\frac{[x][x]}{0.50^{2 }}\\\\3.06 \times 10^{-3}=\frac{x^2}{0.25}\\\\x^2 = 7.65\times 10^{-4}\\\\x=\sqrt{7.65\times 10^{-4}}[/tex]

Answers

When the government decides to decrease government purchases by $250 billion, this will lead to a $175 billion decrease in income.

How to calculate the decrease in income?

From the information, the government decides to decrease government purchases by $250 billion. The decrease in income will be:

= $250 × 0.7

= $175 billion

This decrease in income yet again will cause a second change in consumption equal to:

= $175 × 0.7

= $122.5 billion
